IMPROVEMENT IN DRIP-PIPE TRAPS FOR REFRIGE RATORS.

Specification forming part of Letters Patent No. 132,391, dated October22, 1872.

To all whom it may concern:

Be it known that I, CHARLES DURANT, of Jersey City, in the county ofHudson and State of New Jersey, have invented a new and usefulImprovement in Drip-Pipe Trap for Befi'igerators, of which the followingis a specification:

In the accompanying drawing, Figure l is a detail vertical-section of myimproved drippipe trap shown as applied to a-drip-pipe, and Fig. 2 is atop view of the same, the drip-pipe gazing shown in section through thelines as a,

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved trap for the dripor drain-pipe of a refrigerator, which shall be so constructed that itmay be tilted to clear it of any sediment or other matter that maycollect in it, and unless removed obstruct it and it consists in thecombination of a tilting-trap with the drainpipe; in the construction ofthe trap; in the combination, with the drain pipe, of a U- shapedsupporting and stop bar; in the combination with the trap of a cross-baror plate; in the combination of a trip-rod with the tiltingtrap; and inthe combination of hook-hinges with the trap and its supportingbar, ashereinafter more fully described.

A represents the drip or drain pipe of a refrigerator, about theconstruction of which there is nothing new. B is the drip-pipe trap,which is made wedge-shaped, and is suspended beneath the drip-pipe A insuch a way that the water in said trap may seal the mouth of thedrain-pipe and prevent the passage of air from and into the refrigeratorthrough said pipe. The trap B is made of a single piece of sheet metal,bent at right angles to form'the vertical sides and end, the only jointsor seams being the vertical corners at the vertical end ,of the trap. Tothe lower end of the drip-pipe A, in a horizontal position or nearly so,is attached a U-shaped bar or wire, 0, the bend of which projects at oneside of said drip-pipe and the ends at the other side, said ends beingbent outward for the upper edges 01 the trap to strike against and thusserve as a stop to said trap. To the sides of the trap B, or to across-bar or plate attached to said sides, are attached two hooks, D,which hook upon the bend of the bar or wire 0 and thus suspend the trapB from and-hinge it to said bar or wire. The trap B is suspended alittle out of its center of gravity so that its own weight will hold itin position. The trap B may, if desired, be suspended by a spring, whichwill bring it into position again after being tilted. E is a bar orplate, the ends of which are attached to the sides of the trap B in sucha position that the said plate or bar may be directly beneath thedrip-pipe A. The bar or plate E may be inclined a little toward themouth of the trap B, as shown in Figs. 1 and 2.

When it is desired to tilt the trap to clean out the sediment, a stickor rod may be inserted in the drip-pipe from its upper end, so that thelower end of said stick may rest upon the plate or bar E, which willdepress the mouth of the trap and allow the water and sediment to flowout. As the stick or rod is withdrawn the trap will return to its properposition.

The plate or bar E is especially designed to prevent the end of the rodor stick from slipping down to or past the hinges and being thusunable'to tilt the trap. The hook-hinges D allow the trap to beconveniently detached when desired for thoroughly cleaning it.

In case the upper end of the drip-pipe A be covered with ice, or isinaccessible from any other cause, the trip-rod F may be used. Theforward end of the rod F is pivoted to the trap B forward of its pointof support, and its rear end passes through a guide or keeper, G,attachedto the lower part of the refrigerator or some other suitablesupport. The rod F should have a joint or stop formed upon it, or a stopattached to it in such a position as to strike against the guideGandstop the rod F before the raised end of the trap B strikes the drip-pipeA, which would otherwise form a fulcrum or point of resistance, andproduce a leverage some part of the device.

. Having thus described my invention, I claim as new, and desire tosecure by Letters Patcut-- 1. The combination of the tilting-trap B orits equivalent with the drain-pipe A, substantially as herein shown anddescribed.

that might cause the breakage of 2. A tilting-trap B, made in one pieceof metal, substantially as described.

3. The combination, with the drain-pipe A, of the U-shaped bar or wire0, substantially as shown and described, so that said bar or wire 0 willform both a stop and a support for the tilting-trap. v

4. The combination, with the tilting-trap B, of the cross-bar or plate Efor the purpose of assisting in tilting the trap, substantially asdescribed.

5. The combination of the trip-rod F or its equivalent with thetilting-trap B, substantially as and for the purpose described.

6. The combination of the hook-hinges D with the trap B and itssupporting-bar 0, substantially as described.
